Answer to Question 1

ANS: A
GVHD develops when donor T cells attack and damage patient tissue or tissues. The tissues most likely to be affected vary, depending on whether it is acute (skin, liver, gastrointestinal tract) versus chronic (multisystem autoimmune disease) GVHD.

Answer to Question 2

ANS: C
Proto-oncogenes are genes that code for proteins involved in cell regulation. When these mutate, they are called oncogenes.
